Use instead of + for space in python query parameters

Question

I have written the following python script, using python requests (http://requests.readthedocs.org/en/latest/):

import requests

payload = {\'key1\': \'value  1\         


        

Answer 1

from urllib.parse import urlencode

def to_query_string(params):
    return urlencode(params, doseq=True).replace('+', '%20')

You could pass a string to params instead of a dictionary, and manually handle the spaces.

Maybe something along the lines of

def to_query_string(p, s=''):
    for k in p:
        v = p[k]
        if isinstance(v, str):
            s += f'{k}={v}&'.replace(' ', '%20')
        elif isinstance(v, int):
            s += f'{k}={v}&'
        elif isinstance(v, list):
            for i in v:
                s += f'{k}={i}&'
    return s[:-1]  # remove last '&'

which can be used as

min = 10
max = 30
params = {'query': f'score between {min} and {max}', 'limit': 1, 'information': ['name', 'location']}
response = get('/api/dogs', params=to_query_string(params))
